Water, Waves, and Ships Science

Learn About: Science Water, Waves & Ships - Re-supplying at sea - Severe weather at sea - Stability in wind and waves - Wave action on boats and ships - US Coast Guard search and rescue

Science Water, Waves & Ships On the Internet… Celestial Navigation Traditional Navigation Dead Reckoning Learn More About

Science A Ship’s stability is especially important while re-supplying at seas Science Water, Waves & Ships

Science Typhoon Cobra caught Admiral Hasey’s Third Fleet unaware in December Science Water, Waves & Ships

Science A ship’s stability is related to its buoyancy and weight. Think About This: A large cargo ship is leaving port with its 6 holds (the area in which a ship carries cargo) full. It is going to make several stops. At each port, it will unload some of its cargo leaving a hold empty or partially empty. What can the captain order his crew to do in order to maintain the ship’s stability so that I will not capsize? Engage in class discussion and then restart video clip for demonstration of information required for solution(s). ** PAUSE Video Clip Here! Science Water, Waves & Ships

Science Why would the ship roll? What happens to the ship’s center of gravity when it does roll? Now, think back to Typhoon Cobra. What do you think happened to the ships caught in the typhoon regarding their instability? Science Water, Waves & Ships

Science Waves have several parts: Crest - The highest part of the wave above the still-water line. Trough - The lowest part of the wave below the still-water line. Height - The vertical distance between the crest and the trough. Length - The horizontal distance between each crest or each trough. Science Water, Waves & Ships

Science Waves can cause several different movements in ships: Sway Heave Yaw Waves can affect the navigation of a ship! Science Water, Waves & Ships Go to websites for Waves and tides Ocean currents Tides and the moon Tornadoes Tsunamis

Science How would adding water to the boat’s hull, provide additional stability? * Brainstorm & Research: What Kinds of boat designs would Provide the most stability? Why? Science Water, Waves & Ships

Science Water, Waves & Ships The effects of water and wave action are important elements for navigating a ship and maintaining its stability.
